On Lumi, I love them as lovers, friends, enemies, coparents...they just freaking work whatever way you throw them in a scene...some have their preferences and that is fine...I just think it works out as Sami's best and most honest pairing and she doesn't have to turn into someone she isn't to be paired with him. Lucas doesn't change when he's with Sami and Sami has still been portrayed as a lying, conniving bitch when she's with him....neither change and that is good for both characters in a pairing.
